BARNET VIRGIL IDOL, OF IDOLS MILLS, NORTH CAROLINA.

TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 324,113, dated August 11, 1885.

Application filed May 25, 1885. (No model.)

To all whom it may concern.-

Be it known that I, BARNET VIRGIL IDOL,

a citizen of the United States, residing at Idols Mills, in the county of Ashe and State of North Carolina, have invented certain new and useful Improvements in Turbine \Vater- WVheels, of which the following is a description.

Figure 1 is a side elevation of the turbine water-wheel and easing. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view of the wheel and easing, taken on the line was in Fig. 1. turbine water-wheel inperspective, showing it removed from the casing; and Fig. 5 is a detail view.

This invention relates to turbine waterwheels; and it consists in the detailed construction of the parts, hereinafter fully described and claimed, by which the power of the wheel is largely increased and its construction rendered more simple and convenient of adjustment.

In the accompanying drawings similarletters of reference indicate corresponding parts in all the figures.

A is the casing in which the turbine waterwheel B revolves.

C is the regulating-valve, by which the admission of water to the casing is controlled.

D is the center shaft, by which the motion of wheel B is communicated to the machinery to be driven.

E is a cover secured on top of the casing A,

and provided with openings 6, through which the surplus water may escape from the interior of the casing, and with a bearing, 6, in which the shaft D revolves.

To the bottom of the casing A are attached legs F, provided with feet and with slots f, in which the pivot-arms g are free to slide.

f are screws, by means of which the position of the said arms in the slots can be adjusted.

G is the center pivot, upon which the wheel B revolves and to which the arms 9 are attached, so that the height of the said pivot is adjusted by the position given to the projecting arms 9 in the slotsf.

Fig. 4 is a view of the The wheel B is provided with a recess, 1), at the bottom of it,which fits over the top of the pivot G.

The portions of wheel B, from which it derives its rotary motion, consist of a series of curved arms, 12, situated between the top flange, b and the bottom flange, b, and a second series of arms, I), situated within the thickness of the said bottom flange, b and its continuation If,- which is made somewhat smaller in diameter. The curved arms 1) extend for some distance inward from the periphery of the wheel, but leave an annular open space, 1), round the center casting, which helps to unite the top and bottom flanges. These curved arms 1) form with the top and bottom flanges a series of horizontal buckets having projecting water-guides 11 into which the water rushes and causes the wheel to re volve in the direction of the arrow in Fig. 3. The arms 1) form with the bottom flange and its extension 21 series of vertical buckets situated beneath the first-mentioned horizontal buckets, and through which the water rushes after it has done duty in the said horizontal buckets. These vertical buckets also assist in rotating the wheel and keep it moving in the same direction as the horizontal buckets. The casing A is provided with a flange, a, having a central hole through which the part b of the bottom flange of the wheel projects, while the bottom flange, b revolves freely in the said hole, but does not allow much water to escape. The casing A is not made concentrio with the wheel, but is so arranged that the water has a wide passage where it enters through the regulating-valve O, which passage gradually diminishes as it passes round the circumference of the wheel. After having done duty in the horizontal buckets the water descends vertically through the second series of vertical buckets, which also assist in rotating the wheel. As the central pivot wears away, the vertical height of the wheel can be adjusted by means of the screws f.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a turbine water-wheel, the combination of the shaft D, the flanges b" and b, and the If within a smaller circumference than that extension If thereon, the curved arms b, 10- of the arms b, substantially as shown and decated between the said flanges and extendscribed.

ing from points a little distance from the BARNET VIRGIL IDOL. 5 shaft to points outside of the flanges, forming Witnesses:

the projections b", and the vertical buckets JOHN F. LOGAN,

6, located in the flange b", and the extension FRANK HARDIN.
